Open Graphics Library (OpenGL) is a low level abstract API to interact with graphics processing unit (GPU) to draw 2D and 3D graphics and is a cross-language, cross-platform API typically used to achieve hardware-accelerated rendering, which is faster over software rendering.
OpenGL deals with only rendering and provides, no APIs related to input, audio or windowing.
